Abstract

LA PRESENTE INVENCION SE REFIERE AL CONTROL DE LA VELOCIDAD DE UNA BANDA PARA LA GRABACION Y REPRODUCCION DE INFORMACIONES, POR EJEMPLO UNA CINTA DE VIDEO, EN UN MODO OPERACIONAL EN DONDE LA CINTA PARA EN POSICIONES PREDETERMINADAS. DEBE CONSEGUIRSE CON ELLO UN PROCESO DE FRENADO CORRESPONDIENTE A SER MEJORADO. DE ACUERDO CON LA INVENCION, EN UN PROCESO DE FRENADO AJUSTADO CON EXACTITUD A LA PARADA DE LA CINTA, SE DETERMINA UN DESPLAZAMIENTO OBJETIVO EN EL PRINCIPIO DEL PROCESO DE FRENADO, DEPENDIENDO DE LA VELOCIDAD DE LA CINTA MEDIDA EN ESE PUNTO, SOBRE EL CUAL SON CONTROLADOS Y AJUSTADOS LOS VALORES DE VELOCIDAD ACTUALES. LA INVENCION SE UTILIZA CON PREFERENCIA EN EL CONTROL DE OPERACION DE TIEMPO DE LAZO SOBRE UNA CINTA DE VIDEO.THE PRESENT INVENTION IS RELATED TO CONTROLLING THE SPEED OF A BAND FOR THE RECORDING AND REPRODUCTION OF INFORMATION, FOR EXAMPLE A VIDEO TAPE, IN AN OPERATIONAL MODE WHERE THE TAPE STOPS IN DEFAULT POSITIONS. A BRAKING PROCESS MUST BE OBTAINED ACCORDING TO BE IMPROVED. PURSUANT TO THE INVENTION, IN A BRAKING PROCESS ACCURATELY ADJUSTED TO THE STOP OF THE RIBBON, AN OBJECTIVE DISPLACEMENT IS DETERMINED IN THE BEGINNING OF THE BRAKING PROCESS, DEPENDING ON THE SPEED OF THE RIBBON MEASURED AT THAT POINT, ON THAT POINT. CURRENT SPEED VALUES CONTROLLED AND ADJUSTED. THE INVENTION IS PREFERRED USED IN THE OPERATION CONTROL OF LOOP TIME ON A VIDEO TAPE.
